COLLAPSIBLE TUBE DISPENSER. p

Application led November My invention relates to collapsible tube dispensers, the same being especially adapted for dispensing the contents of paint tubes,

tooth paste tubes, and in fact any materials contained in collapsible tubes. i

It is a well known fact that the handling of collapsible tubes containing paint, or tooth paste is quite undesirable, due to the fact that a considerable amount of the contents frequently become smeared on the outer'side of the tube which must be touched by the user in order to compress the tubes.

The main purpose of my invention is to eliminate entirely this situation by providing a device in which one or more collapsible tubes containing various contents may have their contents easily dispensed without the hands of the user coming in contact with the exterior of the tubes.

rlhe main object of my invention is to provide a device wherein at least one pair of rollers are employed in Contact with each other, and between each of which the bottom end of a collapsible tube is adapted to be inserted for the purpose of dispensing the conf tents thereof.

Stillanother object resides in the means employed whereby each pair of these rolls may be actuated independently of the other 33,112 l A further object resides in the tensioning means whereby the rolls are normally maintained in very snugcontact withy each' other.

Other various novel objects and advantages will become apparent as my device is better understood from the specification and claims to follow.

In the drawing:-

Figure 1 is a side elevation of my device in partial sectional view disclosing the man# ner in which one of the lower rolls is mounted for rotation, and i Fig. 2 is a vertical sectional view taken substantially on the line 2 2 of Fig. 1, and looking in the direction of the arrows.

For a more detailed' description of my invention, l now refer to the drawings, in which like numeralsdesignate like parts of same. A pair of standards 1 and 2, respectively, are mounted perpendicularly on suitable base plates 3 and 4 respectively. Jour- 7, 1927. serial No. 231,610.

naled through the respective standards adj acent their upperV portions are the free ends of a stationaryshaft.

Rotatably mounted on this shaft, are rolls 4, 5 and 6 respectively. It is preferable that these rolls be constructed of wood or other relatively cheap material, while the outer surface "is covered with a resilient material, such as rubber. To one end of each ofV said rolls, a gear wheel 7 is iXedly associated. Spacing collars 8 are disposed between the inner side of the respective standards, and the ends of the respective rolls, while additional spacing collars are disposed between the gears 7 and thi1 respective end portions of the adjacent ro s.

The-end portions of a rod 9 are fixed in the respective standards 1 and 2 respectively, at the lower portion thereof. Arranged upon this rod 9, is a plurality of cylindrical shaped collar members 10, each of said cylindrical collars being formed with a longitudinal bore therethrough, said bore being of elongated extent in cross section, and through which the .rod memberis adapted to extend.

Mounted for rotation upon opposed end portions of the collars 10, are lower rolls 11, 12 and 13 respectively. These rolls are constructed in substantially the same manner as are the rolls 4, 5 and 6, respectively, mounted on the shaft 3. The lower rolls are adapted to be disposed direct-ly under the upper rolls, and adapted to snugly engage each other.

Connecting the respective standards adjacent the lower portions thereof, is a bar 14. Depending from each of said cylindrical collars 10 is a stein 15, the lower endportion of which is adapted to screw thru suitable openings in the bar 14.-. Arranged around each of said stems 15, and disposed between the respective collars and the bar 14, is a coiled spring 16. f

Journaled' for rotation at the upper portion of the standard, is a squared shaft 17, one end portion of which projects beyond the standard 2. To this projecting end portion of the shaft 17 is secured a hand wheel 18.

Adapted for rotation with the shaft 17 and slidably mounted upon the same, is a pin ion gea-r 19. This pinion gear 19 is adapted to be shifted upon the squared shaft 17, whereby itmay be brought into meshed relation with any one of the gears 7 Y Located above the squared shaft 17 and v having their adjacent end portions Vsecured in the respective upper portionsof the standards l and 2 respectively, is a pair of rod n members 2O disposed in a horizontal plane.

A gear shifting jbodyf2l is formed Awithinwardly bent portions 2Q adapted .toencircle members adapted to engagegoppositeEsi'desof ,the pinion 19, At the oppositeen'd'portion of 'the gearshi-ft-body 21afpairfof depending indicating pointers .24 lare provided. The pointed portions of 7these members 24:, are adapted to `be'disposed approximately directlyiover the #center portion of onevof the rollers when the .pinion-gear i9 carried by Ithegea-r shi-ft body :2l is :in meshed relation with` one of the-gear W;heels'7.I v i A'ilhefhandle `25 ,may be provided at `the top of the body 21, whereby the-:same Imay be more A Y conveniently moved on therods;20.

By inserting the tapered bottom portion of a collapsible-tube, fbetween each lpair of rollers, at :theirpoint lof contact, and by lmovj ing :each ofthe rolls 4,55, andlrespectively,

the tube will beimaintainedinposition. For example, to dispensefthezcontents ofatube insertedbetween the rollers 4 yand 11, respectively, fof my fdeviice, las' `is clearly shown in Fig. :l ofthe drawing,:thegearshiftbody 21 is slid alongthe bars 120'until thepointer 2li-is directly-rover the ,'centerportion-'of the roll 4. At this ipoint, itheipinion gear I9 is in meshed relation with the ,gear 7, .1 and :by rotating the hand wheel 18,'1the1pinion 19` will cause the gear on the .rolle to rotate thusly 'causing `the tubeto Ibe fed through and Ibetween the 1respectivefupperandlower rolls. f

'In orderto maintainithelower Toll in prop-V er snug contact with the upper roll, or with the under side J.of the Acollapsible tubefwhen the same is disposed between the rrol1s,"I provide the nov-el :tensioning means disclosed in the drawings. The ,lower rolls are mounted for lrotation on the `cylindrical `collars 10, which are 4formedwith longitud-inalbores therein of Aelongated 4extent in across section.

,The rod extending through I:the collars guide the up and down movement-,o'fgsame, due to fthe tensional pressurero'f @the coiled springs'lG. When the -end offa :collapsible tube is disposed between ythe rolls., the lower roll will be forced downwardly somewhat, thusly :causingthe compress-ion :of the coiled springs, which tensionally support the cylindrical collars upon which that particular roll is rotatable.
